Dork Sahagian is an Armenian American climate scientist. He is the Director of the Environmental Initiative at Lehigh University in Bethlehem, Pennsylvania. He invented a technique for calculating the Earth's air pressure in the past, based on the difference in the size of the bubbles in cooled volcanic lava.

Sahagian contributed to three of four assessment reports by the Intergovernmental Panel on Climate Change (IPCC), which on October 12, 2007 was jointly awarded the Nobel Peace Prize with former vice president Al Gore.
